Raekye (Feb 05 2023 at 01:40): Raekye (Feb 05 2023 at 01:40):The JIT demo in the official repository transmutes the returned pointer to a rust function type. Wouldn't this mean cranelift's compiler backend produces the same ABI as the rust compiler? (And AFAIK Rust doesn't have a stable ABI.) I would have expected it to produce a Rust extern "C" function. I didn't do a thorough search, but I couldn't find documentation on it either. Could someone clarify? Thanks!
bjorn3 (Feb 05 2023 at 13:03):That code is wrong. It should indeed be extern "C". While it is likely to work when only primitive types are passed, it definitively won't work as soon as more complex types are passed.
Raekye (Feb 07 2023 at 03:56):I see, thanks for clarifying! Should someone/I submit a fix to the example? (I don't necessarily want to clutter PRs with trivial changes)
